Sigma Digital SLR Cameras
Sigma digital single-lens reflex camera (also called a digital SLR or DSLR) is a
digital camera that combines the optics and the mechanisms of a single-lens
reflex camera with a digital imaging sensor. The reflex design scheme is the
primary difference between a DSLR and other
digital cameras.
In the reflex design, light travels through the lens, then to a mirror that
alternates to send the image to either the viewfinder or the image sensor. The
alternative would be to have a viewfinder with its own lens, hence the term
"single lens" for this design. By using only one lens, the viewfinder of a DSLR
presents an image that will not perceptibly differ from what is captured by the
camera's sensor.
Sigma DSLRs typically use interchangeable lenses with a proprietary lens mount.
A movable mechanical mirror system is switched down to direct light from the
lens over a matte focusing screen via a condenser lens. Most of the Sigma DSLRs
features a lightweight yet solid magnesium alloy body along with buttons and
connected parts sealed with O-rings, enhancing durability as well as preventing
dust and water from getting inside the camera.
Sigma DSLRs typically use autofocus based on phase detection. Phase-detection
autofocus is typically faster than other passive techniques. Microglobe offer
